NAME

adp - low-level module for Adaptec 7870/7871/7872 based SCSI controllers

SYNOPSIS

adp@reg

AVAILABILITY

x86

DESCRIPTION

The adp module provides low-level interface routines between the common disk/tape I/O system and SCSI (Small Computer System Interface) controllers based on the Adaptec AIC-7870, AIC-7871, and AIC7872 SCSI chip. These controllers include the Adaptec 2940 and 2940W, and 3940 and 3940W, as well as motherboards with an embedded AIC-7870, AIC-7871, and AIC-7872 SCSI chip.

The adp module can be configured for disk and streaming tape support for one or more host adapter boards, each of which must be the sole initiator on a SCSI bus. Auto configuration code determines if the adapter is present at the configured address and what types of devices are attached to the adapter.

The device address, reg, is derived from bits 3-7 of the PCI device number.
